To (0Z7 whmn it may concern:

Be it known that I, Isaac N. ENRIGI-IT, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inGas-Generators, of which the following is a specifica tion.

This invention relates to an improved gas generator, and is especiallyadapted for gen erating water gas from crude oil.

The object of the invention is to provide a gas generator which will besimple and economical to manufacture not requiring any skilled labor toerect and by which the gas can be generated economically.

In the accompanying drawing, Figure 1 is a central vertical section ofthe apparatus; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1:Fig. 3 is a horizontal section on the line 3 -3 of Fig. 1.

Referring to the drawing, it will be seen that the generator is of anelliptical form having an outside casing 1 lined with asbes tos 2 and aninner lining 3 of fire-brick or other refractory material. The interiorof the casing is divided into'three chambers 4, 5 and 6 by brickpartitions 7 and 8 extending transversely across the generator, thefirst partition 7 resting upon piers 9 and extending to the top of theapparatus while the second partition 8 extends from the bottom to anarch 10 extending between the partition 7 and the farther end of thecasing, and forming the bottom of a flue 11. This upper arch issurrounded by a steel channel iron band 21 which prevents the springingout of the arch. Oil for generating the heat for gas making is admittedat the top of the combustion chamber 4 by a pipe 13, and is injected bysteam through a pipe 27. Air for combustion is admitted by a pipe 30,controlled by a valve 31. The flames and products of combustion passdownward through the combustion chamber 4 and between the piers 9underneath the brick partition 7 and up through the heating chamber 5.This heating chamber is illled with checker brick work 14 also supportedupon the piers 9. The products of combustion pass upward through thechecker work and highly heat the same and then pass into the flue 11over the top of the brick partition 8 and down through the superheatingchamber 6. This superheating cham her, in like manner as the heatingchamber 5,

contains checker brick work 16 supported upon piers 17, and the productsof combustion passing down through this checker work highly heat thesame. The waste gases then escape by means of a pipe 18 through a valve19 and may be thence conducted to a stack, not shown.

After the combustion has-been continued for a sufficient length of timeto highly heat the refractory material in the chambers 5 and 6, the oiland air are shut off, and oil is sprayed down into the chamber 5 throughan opening 20. This finely divided oil falling upon the highly heatedrefractory material in the chamber 5 is converted into gas, whichescapes over the partition 8 and down through the refractory material inthe chamber 6 and out by the pipe 18 and by a pipe 22 (the valve 19being now closed) and thence to a washer and scrubber in the usualmanner. In passing over the highly heated reirac tory material in thechamber 6 the oil vapor is converted into a fixed gas. Then the heat inthe chamber 5 has been su'l'liciently reduced by the vaporization of theoil sprayed through the inlet 20, steam is admitted at the opening 13,which steam, passing down through the combustion chamber and up throughthe chamber 5, combines with the hot lamp black deposited upon therefractorymaterial in the chamber 5, and forms therewith water gas,which, passing down the chamber 6 is superheated and converted into afixed gas and passes over and mixes with the gas formed directly byvaporization of the oil, as already explained.

Oil may be also admitted by a pipe 26 to the superheating chamber 6, theinitial temperature of which is less than that of the generating chamber5, and when the heat therein has been sufficiently reduced, this oilsupplied may be shut oil and the operation repeated with the firstgenerating chamber 5.

24 represents man-holes for recheckering. It will be observed that thereisa man-hole at the top of the heating chamber, and also one at thebottom, so that it is possible to rechecker without removing any part except the bricks themselves. 25 is a door for starting the fire.

The combustion chamber 4 being of large size, the result is that theatomized oil is completely burned while in suspension and there is nochance for it to carbonize upon the brick-work.

I claim2- 1. A gas generator comprising a casing'of an elongated closedcurve in horizontal contour, and transverse partitions dividing it intoa combustion chamber at one end, a heating chamber in the middle and asuperheating chamber at the other end, the first partition extendingfrom a point above the bottom of the generator to the extreme topthereof, and the second partition extending from the bottom of thegenerator to a point below the top thereof, checker work in the heatingand superheating chambers, means for admitting oil and air into thecombustion chamber, means for shutting ofl the oil and air, and meansfor admitting oil directly into the heating chamber, substantially asdescribed. 4 i

2. A gas generator comprising a casing of an elongated closed curve inhorizontal c0ntour, and transverse partitions dividing it into acombustion chamber at one end, a heating chamber in the middle and asuperheating chamber at the other end,. the first partition extendingfrom a point above the bottom of the generator to the extreme topthereof, and the second partition extending from the bottom of thegenerator to a point below the top thereof, checker work in the heatingand superheating chambers, piers upon the bottom of the heating andsuper heating chambers upon which the checker work rests, means foradmitting oil and air into the combustion chamber, means for shuttingoff the oil and air, and means for admitting oil directly into theheating chamber, substantially as described.

3. A gas generator comprising a casing of an elongated closed curve inhorizontal contour, and transverse partitions dividing it into acombustion chamber at one end, a heating chamber in the middle and asuper-. heating chamber at the other end, one of said chambers havingman-holes at the top and bottom thereof, the first partition extendingfrom a point above the bottom of the gen erator to the extreme topthereof, and the second partition extending from the bottom of thegenerator to a point below the top thereof, checker work in the heatingand superheating chambers, means for admitting oil and air into thecombustion chamber, means for shutting off the oil and. air, and meansfor admitting oil directly into the heating chamber, substantially asdescribed.

In witness whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
